Abstract
A biopsy device may include a first jaw having a first distal tip configured to pierce tissue, and a second jaw movable relative to the first jaw between a closed configuration where the first jaw and the second jaw are axially aligned, and an open configuration where the first jaw and the second jaw are offset from one another, the second jaw having a second distal tip proximal to the first distal tip in the closed configuration.
Claims20
A biopsy device, comprising:
- a body;
- a piercing tip at a distal end of the body;
- and
- at least one arm positioned proximal of the piercing tip relative to a longitudinal axis of the biopsy device,
- wherein the at least one arm is movable relative to the piercing tip at least between a collapsed configuration and an expanded configuration, and wherein the at least one arm extends radially-outward relative to the longitudinal axis in the expanded configuration.
A biopsy device, comprising:
- an outer member including a distal end that includes one or more beveled surfaces, wherein the one or more beveled surfaces form a piercing tip;
- an inner member including at least one gear rack, wherein the inner member is disposed radially within the outer member and is movable relative to the piercing tip;
- and
- at least one movable arm including at least one gear, wherein the at least one gear is shaped and sized to rotatably engage the at least one gear rack of the inner member,
- wherein the at least one movable arm is configured to move from a collapsed configuration to an expanded configuration relative to a longitudinal axis of the biopsy device, wherein the at least one movable arm extends approximately parallel relative to the longitudinal axis when in the collapsed configuration, and wherein the at least one movable arm extends radially-outward relative to the longitudinal axis when in the expanded configuration.
A biopsy device, comprising:
- a distal tip including one or more beveled surfaces, wherein the one or more beveled surfaces form a piercing tip;
- an inner member including a plurality of gear racks, wherein the inner member is movable relative to the piercing tip;
- and
- a plurality of movable arms including a plurality of gears, wherein each of the plurality of movable arms is positioned proximal of the piercing tip relative to a longitudinal axis of the biopsy device,
- wherein at least one of the plurality of gears is configured to rotatably engage at least one of the plurality of gear racks and in turn cause at least one of the plurality of movable arms to move between a collapsed configuration and an expanded configuration, and
- wherein the plurality of movable arms extend approximately parallel relative to the longitudinal axis when in the collapsed configuration, and wherein proximal ends of the plurality of movable arms respectively extend radially-outward relative to the longitudinal axis when in the expanded configuration.
